What method is used to iterate through arrays in PHP?

There are several ways to iterate through an array in PHP.

1. Traverse the array using a for loop.

$myArray = array("apple", "banana", "cherry");
for($i = 0; $i < count($myArray); $i++) {
    echo $myArray[$i] . "<br>";
}

1. Iterate through the array using a foreach loop.

$myArray = array("apple", "banana", "cherry");
foreach($myArray as $value) {
    echo $value . "<br>";
}

1. Traverse an associative array using a while loop and the each() function.

$myArray = array("name" => "John", "age" => 25, "city" => "New York");
while(list($key, $value) = each($myArray)) {
    echo $key . " => " . $value . "<br>";
}

1. Iterate through an index array using a while loop and the list() function.

$myArray = array("apple", "banana", "cherry");
reset($myArray);
while(list(, $value) = each($myArray)) {
    echo $value . "<br>";
}

Please note that the above methods are suitable for different types of arrays, you can choose the appropriate traversal method based on the array type and requirements.
